what are good cd roms for kids?

Looking for well designed CD Roms for kids starting at age 4. For ex are PBS ( Sesame street et al) Cd Roms good? IE, are they both a good learing tool AND fun for kids? i've seen ones that are a little too easy ( Clifford Phonics CD Rom by Scholastic and Maisy's Playhouse), ie fun but not too educational.
